Frameless Fractionated Stereotactic Radiosurgery for Vestibular Schwannomas: A Single-Institution Experience.

The article presents a study regarding the long term institutional experience of using robotic Fractionated Stereotactic Radiosurgery for Vestibular Schwannomas (FSRS) with a utilized fractionation regime. It cites that the study uses 55 patients with Vestibular Schwannomas (VS) treated with Cyberknife based FSRS at Georgetown University Hospital and results were analyzed using Kaplan-Meier product-limit method. It is inferred that results were biased on whether hypofractionation exists.
